Abstract: Described herein are multifunctional polymers comprising a first repeating unit having at least one pseudo-cationic moiety, a second repeating unit having at least a hydrophobic moiety, and a third repeating unit, where the weight-average molecular weight is less than about 10,000 Da. In one embodiment the polymers exhibit antimicrobial activity. Also provided are compositions formulated with the multifunctional polymers, and a method of providing antimicrobial activity.

Abstract: Provided are multifunctional polymers comprising at least one anhydride repeating unit with at least one pseudo-cationic moiety graft and at least one hydrophobic graft. The grafting functionalizations can occur before, during, or after polymerizing the monomer(s). The anhydride employed may be partially or fully opened to provide amic acids, carboxylic acids, carboxylic acidic salts, imides, esters, and mixtures thereof. The polymers also may comprise other repeating units, including, but not limited to, alpha-olefins. In one embodiment the polymers exhibit antimicrobial activity, and can be employed in a wide variety of compositions, including those where antimicrobial activity is useful. A method of providing microbial activity also is provided.
Abstract translation: 提供了包含至少一个酸酐重复单元与至少一个假阳离子部分接枝和至少一个疏水性接枝的多官能聚合物。 接枝官能化可以在聚合单体之前，之中或之后进行。 所使用的酸酐可以部分或全部开放以提供酰胺酸，羧酸，羧酸盐，酰亚胺，酯及其混合物。 聚合物还可以包含其它重复单元，包括但不限于α-烯烃。 在一个实施方案中，聚合物表现出抗微生物活性，并且可以用于多种组合物中，包括其中抗微生物活性是有用的组合物。 还提供了提供微生物活性的方法。
